The gene density of the tomato BAC sequences containing the Tat and Athila elements. Gene-density of the seventeen tomato BAC sequences containing the Tat and Athila elements is presented. The gene density of the 'Gene-rich region' depicted by the gray column indicates the average gene density of the compared tomato gene-rich sequences. The gene number was counted with the exception of the transposable element genes. The gene density of the fifteen BAC sequences was lower than that of the gene-rich region by at least three times. The gene-density of the remaining two BAC sequences was similar to that of the gene-rich region. No genes were found in the C08SLe0111P08.1 and C08HBa0074F18.1.
